Description: Use keys to change lanes. Avoid other cars at all cost! To make a car disappear calculate the sum of the digits that appear on its license plate. For example: For 26 press 8 (2+6=8).
If the sum is 10 or higher recalculate the sum of the digits. For example: For 268 press 7 (2+6+8=16; 1+6=7). Have fun!
